I took this just a few weeks ago with a Nikon D7100 and a Sigma 50-150mm f/2.8 lens. I was at the Zoo... I really don't like the zoo but there are many easy opportunities for practice there. I have a photography class tonight and unfortunately am bringing none of my assignments which isn't very good. I've been feeling ill and the weather hasn't been that great. Fortunately, I have 3 days off this weekend to catch up!
As I progress in my Lightroom class I might try to tweak the photo a bit. Some folks suggested I sharpen his eyes and remove some leaves and branches.
I'm not a big fan of tweaking photos. I prefer to completely compose the picture when I take it and let it stand as is. However, I must admit that I will straighten out a photo on my computer if it is a bit crooked.
That being said, I think your image of the lion is excellent as it is.
